🚀 Domain Information Gathering Script 🚀

🤔 What does this script do? This script is designed to gather various information about a domain, including:

• Resolving the domain name to an IP address 📊
• Retrieving the Autonomous System Number (ASN) 📈
• Fetching the Classless Inter-Domain Routing (CIDR) block 📊
• Converting the CIDR block to IP ranges 📈
• Performing a Reverse DNS lookup on the IP ranges 🔍

📊 Comparison with Existing Tools: This script outperforms existing tools in several ways:

🔍 Nmap:

• Nmap is a powerful network scanning tool, but it requires multiple commands to gather the same information as this script.
• This script provides a more streamlined and user-friendly experience.

🔍 Dig:

• Dig is a DNS lookup tool that can resolve domain names to IP addresses, but it doesn't provide ASN or CIDR information.
• This script builds upon the functionality of Dig and adds additional features.

🔍 Whois:

• Whois is a tool for retrieving domain registration information, but it can be cumbersome to use and requires manual parsing of the output.
• This script automates the Whois lookup process and extracts the relevant information.

🔍 Other Scripts:

• Other scripts may provide some of the same functionality, but they often require manual configuration and can be difficult to use.
• This script is designed to be easy to use and provides a comprehensive set of features.

📈 Features:

• Resolves domain names to IP addresses using Dig
• Retrieves ASN information using Whois
• Fetches CIDR blocks using Whois
• Converts CIDR blocks to IP ranges using Prips
• Performs Reverse DNS lookups on IP ranges
• Saves output to files for easy reference
• Provides a user-friendly interface for selecting which information to gather

🚀 Benefits:

• Saves time by automating the process of gathering domain information
• Provides a comprehensive set of features for domain analysis
• Easy to use and requires minimal configuration
• Outputs are saved to files for easy reference

📝 Installation Steps: 1️⃣ Install the required tools:

• dig for DNS resolution
• whois for ASN and CIDR retrieval
• prips for CIDR to IP range conversion (optional)

On Ubuntu-based systems:

bash
sudo apt install dnsutils whois prips

2️⃣ Download the script:

bash
git clone https://github.com/povzayd/dnsdigger.git
cd dnsdigger

3️⃣ Make the script executable:

bash
chmod +x dnsdigger ptrcleaner

🚀 Usage: 1️⃣ Run the script with the domain name as an argument:

bash
./dnsdigger example.com

2️⃣ Follow the prompts to choose which information to gather:

• Fetch CIDR block? (y/n)
• Convert CIDR to IP ranges? (y/n)
• Perform Reverse DNS lookup? (y/n)

📄 Output: The script will save the output to the following files:

• ${domain}_ip.txt: Resolved IP address
• ${domain}_asn.txt: ASN number
• ${domain}_cidr.txt: CIDR block (if fetched)
• ${domain}_ip_ranges.txt: IP ranges (if converted)
• ${domain}_reverse_dns.txt: Reverse DNS results (if performed)

#PTR Cleaner A Bash script designed to extract and clean domain name pointers from a given text file.

Purpose: This script simplifies the process of extracting domain name pointers from a text file, typically containing PTR records. It removes trailing dots from the extracted domain names, providing a clean output.

Features:

• Prompts user for input text file and output file name
• Checks if the input file exists before proceeding
• Extracts domain name pointers using grep with a Perl-compatible regular expression
• Removes trailing dots from the extracted domain names using sed
• Saves the cleaned domain names to the specified output file

Usage:

1. Make the script executable: chmod +x ptrcleaner.sh
2. Run the script: ./ptrcleaner
3. Enter the input text file and output file name when prompted

Example Output: Suppose the input file ptr_records.txt contains:

pointer example.com.
pointer subdomain.example.com.
pointer anotherdomain.net.

Running the script and specifying ptr_records.txt as the input file and cleaned_domains.txt as the output file will result in:

example.com
subdomain.example.com
anotherdomain.net

being saved to cleaned_domains.txt.
